Editing How to Add Consecutive Integers from 1 to 100

There are a few different methods you could use to add consecutive integers from 1 to 100. Here are three possible approaches:

1. Use the formula for the sum of an arithmetic series:
The sum of the first n positive integers can be found using the formula:
sum = n * (n + 1) / 2
For the sum of integers from 1 to 100, we have n = 100, so we can plug this into the formula and get:
sum = 100 * (100 + 1) / 2
sum = 50 * 101
sum = 5050

2. Use a loop in a programming language:
If you're comfortable with programming, you could use a loop to add the numbers together. Here's an example in Python:
sum = 0
for i in range(1, 101):
    sum += i
print(sum)

This will output 5050, which is the sum of the consecutive integers from 1 to 100.

3. Add the numbers manually:
If you prefer to do things by hand, you can simply add the numbers together one by one. You might find it helpful to group the numbers into pairs (e.g. 1 + 100, 2 + 99, 3 + 98, etc.) to make the process go faster. Here's what the first few pairs would look like:
1 + 100 = 101
2 + 99 = 101
3 + 98 = 101
4 + 97 = 101
...
50 + 51 = 101

Notice that each pair adds up to 101, and there are 50 pairs in total. So we can simply multiply 101 by 50 to get the sum:
sum = 101 * 50
sum = 5050

So there you have it - three different ways to find the sum of consecutive integers from 1 to 100!
